On the other hand, it is in off working state at x-axis motor 90, y-axis motor 94, θ motor 104 and only makes P motor 46 work In the case of work, in the case of assuming to there is not error etc., a pair movable piece 80a, 80b should on xc axle linearly phase mutual connection Closely/separate.Central point C is in identical point all the time, and axis alpha should be consistent with xc axle.But, in practice, such as Figure 12 (a)~figure Shown in 12 (d), there are a pair respective physical location of movable piece 80a, 80b (representing with the circle of thick line) from target location The situation that (representing with three layers of circle) deviates.It addition, along with the deviation of a pair movable piece 80a, 80b, such as Figure 12 (b), Figure 12 Shown in (d), there are following situation: virtual center point C* of movable piece 80a, 80b also deviates from target's center's point Cref, actual Axis alpha * tilts also relative to xc axle, and actual pitch P* also becomes and the target distance corresponding to the control instruction value of P motor 46 The size that Pref is different.
On the other hand, with first movable part 40a, 40b, there is driving at spacing change device 44 the most one by one In the case of source, at central point C on xc axle (on the axis that a pair movable piece 80a, 80b pass through) in the case of deviation, it is possible to Central point C is made to put Cref close to target's center by the independent control driving source.But, for a pair movable piece 40a, In the case of 40b has a driving source, it is difficult to come correction center point C's by this control driving source (P motor 46) Deviation.It addition, in the case of departing from from xc axis at central point C and deviateing, even if in the case of possessing independent driving source, Also the deviation of correction center point C it is difficult to.
Then, in the present embodiment, lead elements and production method thereof is not being carried out in the case of the assembling of substrate P, in other words, not Under the state of carrying substrate P, make target distance Pref change, make the control instruction value of P motor 46 change, while obtaining real The respective position of movable piece 80a, 80b on the border departure far from target location.Actual movable piece 80a that further, use obtains, The departure of the respective position of 80b, obtains (x) virtual center point C* departure (the central point deviation away from target's center's point Cref Amount), (y) actual deviation (misalignment of axe by the angle between axis alpha * and object axis α ref of movable piece 80a, 80b Angle), departure (spacing deviation amount) between actual pitch P* of (z) movable piece 80a, 80b and target distance Pref, will be with mesh Relation table between mark spacing (or control instruction value) format (following, to would indicate that the form of these relations is referred to as deviation form) and Storage.Further, based on the departure obtained from deviation form, obtain corrected value, based on corrected value, generate for x-axis motor 90, The control instruction value of y-axis motor 94, P motor 46, θ motor 104 etc..Hereinafter, the target being changed when obtaining deviation form Spacing is referred to as setting spacing.This is to distinguish with the target distance in actual control.
Additionally, the departure that might not obtain between physical location and target location, it is also possible to only obtain two movably The physical location of part 80a, 80b.It reason for this is that, target location is known.
{ acquirement of deviation form }
By perform Fig. 9 flow chart represented by deviation obtain program, obtain movable piece 80a, 80b physical location with Departure between target location, obtains deviation form.In this program, set spacing P and be worth P0 and end value P (n) in the early stage Between periodically change in units of Δ P.
In step 1 (hreinafter referred to as S1.The most identical for other steps), in S2, cut off clenching unit 34 and pass through unit Mobile device 36 and move horizontally towards predetermined locating, make cut-out clench the coordinate system (xc, yc, zc) of unit 34 with (x, y, z) consistent mode rotates around plumb line with the coordinate system of lead elements and production method thereof assembly machine.In S3, set spacing P (j) and set For initial value P0 (j=0).In S4, it is judged that { whether=P0+j Δ P:j=0~n} is end value P (n) to set spacing P (j) {=P0+n below Δ P}.Owing to being judged as "Yes" in the case of initially performing S4, therefore in S5, according to setting spacing P0 generates control instruction value and controls P motor 46.In this condition, in S6, S7, by camera 30 actual photographed a pair respectively Movable piece 80a, 80b, thus obtain view data.Further, based on the view data obtained, movable piece 80a, 80b are obtained each The physical location departure away from target location, in S8, set up corresponding relation with setting spacing P0 and store.
In detail, clench control portion 148 from cut-out and export " the shooting instruction of movable piece 80a, 80b ".Insert at element In device 16, make operation 20 towards primary importance (movable piece can shooting in movable piece 80a, 80b, i.e. movable piece 80a Position) mobile, by one movable piece 80a of camera 30 actual photographed.Then, operation 20 is made (can to clap towards the second position Take the photograph the position of another movable piece 80b) mobile and actual photographed another movable piece 80b.Further, control portion 146 is inserted from element defeated Go out obtained view data, and clench control portion 148 in cut-out and receive this view data.In cut-out clenches control portion 148, Obtain the position on actual (xc, yc) coordinate of movable piece 80a, 80b, obtain the departure between target location.Such as, In the case of Figure 12 (a) Suo Shi, it is respectively directed to movable piece 80a, 80b, obtains movable piece 80a, 80b with being shown below each The physical location departure { x-component on coordinate (xc, yc), y-component } away from target location.
Da (0)={ dxa (0), dya (0) }
Db (0)={ dxb (0), dyb (0) }
Further, in S9, make setting spacing changes delta P, in S10, make j increase by 1, in S4, it is judged that to set spacing P (1) be whether end value P (n) below.Now, owing to being judged as "Yes", the most repeatedly perform S5~S10.Hereinafter, between setting Being end value P (n) period below away from P (j), repeatedly perform S5~S10, make setting spacing P (j) changes delta P every time, acquirement can Departure between the respective physical location of moving part 80a, 80b and target location.Wherein, ratio is become finally when setting spacing P (j) When value P (n) is big, the judgement of S4 is "No", in S11, generates deviation form.
In S11, it is based respectively on the departure { da (j), db (j) } of the position of movable piece 80a, 80b of acquirement, obtains X () spacing deviation amount dp (j), (y) misalignment of axe angle d θ (j), (z) central point departure dC (j), set up with setting spacing P (j) Corresponding relation also stores.Such as, in the case of Figure 12 (b) Suo Shi, obtain spacing deviation amount dp (k-1), central point inclined Residual quantity dC (k-1)={ dx0 (k-1), dy0 (k-1) }, misalignment of axe angle d θ (k-1), set up corresponding closing with setting spacing P (k-1) It is and stores, in the case of Figure 12 (d) Suo Shi, obtaining spacing deviation amount dp (k+1), central point departure dC (k+1) ={ dx0 (k+1), dy0 (k+1) }, misalignment of axe angle d θ (k+1), set up corresponding relation with setting spacing P (k+1) and deposit Storage.
Setting spacing P (j) that obtains as described above shown in Figure 11 (a), Figure 11 (b), Figure 11 (c), spacing deviation Measure an example of the relation between dp (j), misalignment of axe angle d θ (j), central point departure dC (j), i.e. deviation form.Expect In advance obtain deviation form, and be stored in advance in cut off clench control device 148 storage part.
Additionally, Δ P both can be positive value, it is also possible to be negative value, setting spacing both can be cumulative, it is also possible to decrescence.
It addition, deviation form might not be previously generated and stores in advance.It reason for this is that, as long as between clearly setting The physical location away from P (j) and a pair movable piece 80a, 80b relation between the departure of target location, can obtain every time Spacing deviation amount dp, misalignment of axe angle d θ, central point departure dC.
